Two paricles A and B start simultaneously from the same point and move in a horizontal plane. A has an initial velocity `u_(1)` due east and acceleration `a_(1)` due north. B has an intial velocity `u_(2)` due north and acceleration `a_(2)` due east.

A

Paths followed by the particles must intersect at a point

B

Particles must collide at a point

C

Particles will collide if `a_(1)u_(1)=a_(2)u_(2)`

D

Particles will attain same speed at some point of time if `u_(1) lt u_(2) and a_(1) gt a_(2)`

Text Solution

Verified by Experts

The correct Answer is:
A, C, D
(a,c,d): Path for both the particles are shown in the figure . Initial velocity should be tangent to the path and path should curve according to the aceeleration . We can see that the paths followed by both the particles must intersect each other . Hence , option (a) is correct .

    Two points P and Q move in a straight line AB. The point P starts from A in the direction AB with velocity u and acceleration f and at the same time Q starts from b in the direction of BA with velocity u_(1) and acceleration f_(1) . If they pass one another at the middle point of AB and arrive at the other ends of AB with equal velocities, then (u+u_(1)) (f-f_(1)) = 8 (fu_(1)-f_(1)u).
